Though theoretically the comic strip was a sort of continuation of the original prozine stories, damon knight recalls a "curious fact, which I'd never seen mentioned anywhere, that Nowlan/Calkin' Killer Kane looked exactly like Bold's drawings of Blackie DuQuesne [in E. E. Smith's The Skylark of Space] and although the first few strips were based roughly on the Nowlan story, next thing you know (or anyhow, next thing I remember) Kane has kidnapped the heroine in a spherical spaceship and the hero is in hot pursuit.
